BARREL-HEAD RETAINER.

Specification of Letters Patent. Patented J uly 21, 1914.

Application filed December 10, 1912. Serial No. 735,984.

T all whom it may concern Be it known that I, EDWARD W. Ron' NsorI, acitizen of the United States, residing n Savannah, Georgia, haveinvented certaln Improvements in Barrel-Head Retainers, of which thefollowing is a specification.

The object of my invention is to provide a retainer for the heads ofbarrels, especially barrels'of that type in which the staves areinterwoven with airs of wires twisted together between t e staves. Thisob ect I attain in the manner hereinafter set forth, reference bein hadto the accompanying drawing, in w ich Figure 1 is a sectionalperspective view of part of a barrel and barrel head with retainer forthe latter'constructed in aocord-' ance with my invention; Figs. 2 and 3are, respectively, perspective views of parts of the different membersof the retainer sepa-- rated from one another; Fig. 4 is a similarperspective view illustrating the preliminary stage in the operation ofuniting the membersof the retainer, and Fig. 5 1s a similar perspectiveview illustrating the final stage in the operation.

In Figs. 2, 3, 4 and 5 the members of the retainer are shown in thestraight positlon -which they occupy before the retainer is bent intothe hoop form which it assumes before being applied to the barrel.

In Fig. 1 of the drawing, 1-1 represent certain of the staves of thebarrel and 2-2 certain of the sections of the head of the same. Thestaves are interwoven with pairs of wires 3, 3 which are twistedtogether between successive staves so as to retain the latter in properrelation to one another to form the desired bilged barrel, as set forthin my ap 9, 1910, erial No.59 5505.

The end pair of wires is located some little distance inwardly from theends of the States and the inner wire 3 of said end pair I provides asupport for the barrel head, the

shown in Fig. 1. The

peripheral ortion of the inner face of said arrel hea bearing u on thewire/13, as oop orremmer for the barrel headis of inverteidflhnpp incross section so as to fit snugly over tht-ends of theptaves and itiscom osed of an outer member 4 lyin against t e outer faoes'of the stavesa-n an inner member 5 1 ing againat the inncr'facesof the same, saiinlication for atent filed November 9 of the retainer i ner memberhaving at its lower edge an inturned flange 6 which bears upon the outerface of the peripheral portion of the head and serves to confine thesame firmly to its seat u on the inner wire 3 of the end pair, as sho nin Fig. 1.

The outer member 4 of the retainer has a semi-circular head 7 formedthereon, which bead engages with the outer wire 3 of the end pair, asshown in Fig. 1, and downwardly beyond said bead 7 the outer mem ber ofthe retainer has an outwardly flaring flange 8 so as to facilitate theslipping of the inner portion of the outer member 4 of the retainer overthe wire 3 when the retainer is pressed onto the ends of the staves.

The two members of the retainer are united by means of an interlockjoint at the outer corner of said retainer, which joint is formed in thefollowing manner: Both members of the retainer are originally straight,

the inner member 5 of the retainer having at the to an outwardlyprojecting portion 9 of a width equal to the thickness of the staves,this portion constituting the top of the completed retainer and having,at its outer edge, an upstandin flange 10. The outer member 4 of theretainer has at the top a downturned flange 11 which'is first fittedover the upturned flange of the inner member, as shown in Fig. 4, theengaging flanges being then bent down over the to 9 of the retainer, asshown in Fig. 5. he straight members of the retainer when thus lockedtogether are then bent into hoop form and the meeting ends are united bywelding or any other available means, so as to permanently maintain theretainer in the hoop form..

As the outer portion of the horigontal top when the latter is'bent intohoop form, 0 greater diameter than the inner portion, I provide for. thenecessary expansion of such outer portion by formin slits 12 atintervals in said top 9,-

The flange 6 and the interlocked fliuigee 10 and 11, which occupy ahorizontal position in the retainer, are, while the parts of theretainer are in the straight condition, ndtched,as shown at 13 in Figs.2, 3 and 4 so that when the retainer is bent into hoop form the innerportions of said flanges can contract sufiiciently to compensate for thelesser diameter of said edges as compared with the outer edges of theflanges.

The hook-like retainer is intended to be applied to the projecting endsof the staves l by pressure so thatit retains its position partly byreason of the engagement of the bead 7 with the outer wire 3* of the endpair and partly by reason of its frictional hold u on the ends of' thestaves. The retainer a so serves to bring the ends of the staves intoproper registry with one another and thus perfects the symmetry of theend of the barrel while at the same time it armors the ends of thestaves and protects them from injury which might otherwise be caused byrough handling of the barrel, the four'thl'cknesses of metal at theouter corner of the retainer rendering this part of the same extremelyrigid and well calculated to resist the blows upon it caused when thebarrel is dropped endWise upon the ground or upon a floor or platform,or when the barrel is being rolled while supported upon the ends of thestaves.

I claim 1. The combination of a barrel composed of staves interwovenwith pairs of wires, a head resting upon the inner wire of the end pair,and a retainer of inverted U-shape in cross section, said retainer beingpassed over the ends of the staves and the inner member of the retainerhaving an inwardly projecting flange overlapping the peripheral portionof the barrel head so as to maintain said head upon its seat on theinner wire, the outer member of the retainer having thereon a hollowbead for engaging the outer wire of the end pair, and said outer memberof the retainer havin beyond said hollow head a flaring flange orfacilitating the engagement of said outer member of the retainer withsaid outer wire.

2; A barrel head retainer consisting of inner and outer membersone lyingagainst the inner faces of the staves and the other against the outerfaces of the same, the inner member having an inwardly projecting flangefor engaging the barrel head and said members being united byinterlocked flanges at the outer corner of the retainer and beingretained in rigid relation to one another by reason of said interlockedflanges.

3. A barrel head retainer consisting of inner and outer members onelying against the inner faces of the staves and the other against theouter faces of the same, the inner member having an inwardly projectinflange for engaging the barrel head and sai members being united byinterlocked flanges located at the outer corner of the retainer and bentdown upon the top of the same and being retained in rigid relation toone another by reason of Said interlocked flanges.

4. A barrel head retainer consisting of inner and outer members onelying a must the inner faces of the staves and t e other against theouter faces of the same, the inner member having an inwardly projectingflange for engaging the barrel head, said members being united byinterlocked flanges at the outer corner of the retainer, and beingretained in rigid relation to one another by reason of said interlockedflanges, and the outer member of the retainer having a hollow beadformed thereon for engaging a wire which constitutes part of the barrelstructure. 7

5. A barrel head retainer consisting of inner and outer members onelying against the inner faces of the staves and the other against theouter faces of the same, the inner member having an inwardly projectingflange for engaging members being united by interlocked flanges locatedat the outer corner of the retainer and bent down. upon the top of thesame, and being retained in rigid relation to one another by reason ofsaid interlocked flanges, and the outer member'of the retainer having ahollow bead formed thereon for en.-

gaging a wire which constitutes part of the barrel structure.

6. A' hoop-shaped retainer for barrel heads, said retainer beingUQf-shaped in cross section and comprising twomembers united at theouter corner of the retainer by airinterlocked horizontal joint, thecomponent parts of which joint are notched so as to facilitate thebending of the retainer into hoop form In testimony whereof, I havesigned my nameto this specification, in the presence of two subscribingwit sses.
